they are attached, thus supplying the lubri-v cating material when and while it is required,

Y and cutting oii the supply when no longer necessary.

Our lubricator is intended principally for use on the cylinders of steam, blast, and gas ,y through ordinary lubricators.

engines, the valve in the lubricator which regulates the supply oi' the lubricant being acted upon and worked directly by the steam, air, or other compressed vapor or gas in the cylinder, chest, pipe, or other part to which it is connected. The lubricator is peculiarly adapted to the use' of dry plumbago, grease, and oils which are too thick to pass freely lu the drawings, Figure 1 is a plan or top Aview of the lubricator. Fig 2 is a vertical section of the same. Fig. 3 is an enlarged elevation of the reciprocating valve, and Fig. 4 is a cross-section of the valve onthe line y e.

This valve, Figs. 3 and 4, is composed of two l principal parts, the upper and largest part hai/ing thc face d, 'the wingsf, and the screw Upon the screw is carried a smaller part or valve, j, having the face e. y The part j may be tapped to fit the screw z'- and fixed on the screw at any pointby the jam-nnt'c, or it may be secured in any other convenient way which B is a stop cock or valve, preferably having its upper' end enlarged to receive the neck of the reservoir A.

The throat T in the neck of the reservoir is 'provided at each end with the valve-seats The valve C works up and down g and h. in this throat, being guided by the wingsf, the valve-faces d and e making contact with the valve-seats g and h, respectively, of the throat. p

L is a pipe, by which the lubricator may bc conveniently connected to the cylinder, 81o., requiring lubrication.

M is` a close-fitting coverJ secured by the f hand-screw N and yoke l).

Theaction of the lubricator is as 'followsf Wvo will suppose it connected to the top head of the air-cylinder of a vertical blowing-engine, and the lubricant used to be pulverized plumbago in adry state. The reservoir A is not quite iilled with plnmbago, the cover M replaced, and the stop-cock turned wide open. As the piston risesin the blowing-cylinder the contained air is compressed, and communicating with the lubricator through the pipeA L it exerts itself against the valve C, which is forced up until its face c is niet by the seat hf. The plumbago will be disturbed by :the entering air; but on the closing of the valve (by the contact of e and h) it will at once settle,

a limited quantity falling into the throat T Vbetween the wings f and'below `the face d of the valve C. Then the pressure of air is re` lieved by the4 4descent of the piston in the blowing-cylinder, the` if'alve C will fall, allowing its charge or' plumbago to drop into the cylinder and be distributed bythe incoming air. The air, which during the upward stroke of the piston passes the valve C and is compressed in the reservoir A., serves to blow the charge of plumbago out of the throat T at the dropping of the valve. This process will oi' course be repeated at each stroke of the engine. The charge-may be regulated by alter ing the distance between the faces 'd and e of the valve C, as already described.

The particular use of the stop-cock B is to temporarily cut off communication to the lubricator While itis being chargedwith lubrig and h, the valve C having two faces, d and e, 1o cant, 01 while the Valve C is being taken out with a. chamber between said faces,and the for adjustment, and for the facilitation of re- Valve or stop-cock B below the valve C, all
